BEER-PUMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 620,463, dated February 28, 1899.

Application filed May 16, 1898. Serial No. 680,888. (No model.)

T to whom it may concern.-

Be it known that we, ALVAH O. LATIMER and WILLIAM D. CRENSHAW, citizens of the United States, residing at Cedar Rapids, in

the county of Linn and State of Iowa, have invented certain new and useful Improvements in Beer-Pump Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which I 5 and the nature of the invention is fully disclosed in the description and claim following, reference being had to the accompanying drawings, forminga part of this specification.

In the drawings, Figure 1 is a side view of Fig. 2 is a central longitudinal section of the device in a vertical plane and a fragment of the adjacent keg.

Similar letters of reference indicate correz 5 sponding parts.

3 o monly done with a device known asa beerpump, a somewhat complicated and quite expensive apparatus. The device embodying this invention is designed to accomplish the same purpose by very simple and inexpensive means, as will appear from the description following.

Referring to the drawings, A designates an ordinary beer-keg provided with the usual faucet B. In some suitable hole near the upper partof the keg-the head, for example is inserted a hollow metallic plug C, suitably tapered so as to be driven tightly in place and closed at the outer larger end by a head 0. At one side of the plug, near the closed end or in the end itself, if preferred, is placed a small check-valve 0 adapted to connect with the terminal coupling of a small airpump D.

In practice the check-valve is of the kind commonly used for bicycle-tires, and any bicycle air-pump may be used for inflation.

The pump may remain attached to the checkvalve or nipple, as it is generally called, or detached, the compressed air being retained bythe check-valve, as in the case of a pneumatic tire. g

It will be observed that the outer end of the plug is inset, so that in driving the plug home the blows fall on the edge of the conical tube and not on the head, which is secured in the tube in some simple manner, as by soldering.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The herein-described air-pump attachment for beer-kegs and the like, composed of a tapered metallic tube, an inset head secured in the larger end, and a check-valve near said head, adapted to connect with an air-pump.

In testimony whereof we affix our signatures in presence of two Witnesses.
